CHEMICAL PHOTO ETCHING
Chemical photo etching is a process used to create intricate metal designs or components by selectively removing metal from a sheet or plate. The process involves the use of a photosensitive material called a photoresist, which is applied to the metal surface. The photoresist is then exposed to UV light through a stencil or pattern, causing it to harden in the exposed areas.
The unexposed areas of the photoresist are then dissolved away with a chemical etchant, leaving behind the desired design or component. The metal sheet is then washed and dried, and the remaining photoresist is removed.
